Ash is the third most common tree in Britain, it can live for up to four hundred years, more if coppiced. The wood is commonly used for tool handles and baseball bats where its ability to resist shock without splintering is valued.

A fully-grown tree can reach a height of 35m. Tall and graceful, they often grow together, forming a domed canopy. The bark is pale brown to grey, which fissures as the tree ages. Easily identified in winter by smooth twigs that have distinctively black, velvety leaf buds arranged opposite each other.

In earlier times the ash tree was thought to have medicinal and mystical properties and the wood was burned to ward off evil spirits. In Norse Viking mythology, ash was referred to as the ‘Tree of Life’. In Britain ash has been referred to as a healing tree.

The ash is often the last tree to come into leaf in the spring, especially if the weather is cold and the sun doesn’t shine as ash trees are responsive to light.

The ash tree was thought to have medicinal and mystical properties and the wood was burned to ward off evil spirits. In Norse Viking mythology, ash was referred to as the ‘Tree of Life’. Even today it is sometimes known as the ‘Venus of the woods’. In Britain we regarded ash as a healing tree.

In recent years the ash has come under threat from the fungus Hymenoscyphus fraxineus causing the condition known as ash dieback. It blocks the water transport systems in trees causing leaf loss, lesions in the wood and on the bark and ultimately the dieback of the crown of the tree.

This disease was first described in Poland in 1992 and has since swept westwards throughout Europe. It was first identified in Britain in 2012 in nursery stock then in the wider environment in 2013 although it could have been in the country much longer.

The number of confirmed findings is continuing to increase and the distribution is reported by the Forestry Commission on a regular basis.

Young trees are particularly vulnerable and die quickly once they succumb. Older trees can be slowly killed by a yearly cycle of infection. Spread of the disease in the UK is most likely to be as a result of the planting of infected nursery stock and wood but wind-borne distribution of the fungal spores also occurs.

There are several key signs to look out for, for example, saplings have dead tops and side shoots. In mature trees, dieback of twigs and branches in the crown, often with bushy growth further down the branches where new shoots have been produced

All of these symptoms can also be caused by other problems, so final diagnosis should be made by an expert tree surgeon. Summer is a good time to look for symptoms as in autumn and winter, ash trees will naturally be shedding their leaves making it difficult to identify ash dieback.

One hopeful sign is that British ash trees seem to have better resistance ash dieback than those in mainland Europe according to research which has decoded the DNA of the species for the first time.
